Embodiment 1

[0040] Fig. 2 shows a practical scheme in which the platform of the present invention enables three probes and samples to work in the same micro-area. In this solution, the probe positioning drive system and the sample positioning drive system are respectively composed of three parts: a positioning track system, a stepping drive system and a piezoelectric crystal drive system (see Figure 3). The position of the sample is determined by the position of the sample stage on which it is placed.

[0041] The probe orientation track system in this scheme is a centripetal track system, including:

[0042] (1), determine the probe longitude rail 0 of the probe longitude;

[0043] (2), the probe latitude guide rails 2-1, 2-2, 2-3 for locking the longitude of the probe and determining the latitude of the probe, each guide rail is an arc greater than 1 / 4 circumference;

[0044] (3), the positioning rotating shaft 2-0 of the probe latitude guide rail.

[0045] The longitude guide rail o...

Embodiment 2

[0060] The research and development platform of the present invention docks two probe tips to form an example of a one-dimensional nano junction (see Figure 4).

[0061] 1. In this example, the tip of the probe is an exposed surface of a nano-microstructure, which can form a nano-research object or a part of the structure. On the basis that the probe step driving system makes the tips of the probes 1-1 and 1-2 relative (see accompanying drawing 4), the system workstation 15 controls the platform piezoelectric crystal drive power supply 12 to make the two heterogeneous probes The needle tips of the needles 1-1 and 1-2 (N-type and P-type) are relatively close to produce a tunnel effect, and then scan each other to determine the atomic arrangement structure on each other's surfaces. The system workstation 15 selects and makes appropriate surface structures close to each other by controlling the stepping drivers 5-1 and 5-2 of the rotation angle until "contact" forms a one-dimensi...

Embodiment 3

[0066] An example of the interaction between two probes and nanowires illustrates how the platform forms a multifunctional "nano-manipulator" for microstructure processing, manipulation, assembly, and control (see Figure 5).

[0067] 1. The system workstation 15 drives the stepping drivers 3-1, 4-1, 5-1 of the probe 1-1 and the stepping drivers 9, 16 of the sample stage through the stepping drive power supply 11 of the control platform, so that the probe 1-1 Approach different parts of the nanowire 19 on the sample substrate; the workstation 15 instructs the platform signal generation system 13 to generate a bias voltage to be applied between the sample and the probe, and at the same time instructs the platform signal acquisition and amplification system 14 to collect the gap between the sample and the probe. tunnel current, according to the size of the detected tunnel current, a feedback control command is sent to the piezoelectric crystal drive power supply 12 to drive the pr...

Abstract

It is a multi-function nanometer research and develop workbench, which comprises the probes able to control accurately positions and samples. The multiple probes are made of same or different materials and undertake same or different functions or the combination. The multiple probes or samples together work in same micro area and exert effect on the study subject and generate inspiration and measurement functions and also become the components of the study subject and certain structure and display the position, shape, structure and state of the study subject.

Description

technical field [0001] The invention relates to a device capable of studying the properties of atoms, molecules, and nano-units and their interactions with substrates and operators, realizing operations, processing and combining nano-scale objects, and performing nano-micro-mechanism systems. A research and development system for assembly, testing, and manipulation—a multifunctional nano research and development platform. Background technique [0002] Field emission microscopy is the first microscopic technique to achieve atomic-scale resolution. Its working mechanism is the tunneling effect of electrons, and the research object is a needle-shaped sample, which can be used to determine the microscopic atomic structure of the probe tip. [0003] Scanning tunneling microscopy (STM) is not only a tool for probing the atomic structure of surfaces, its use to achieve certain artificial arrangements of atoms suggests that it is also a means of manipulating atoms to some extent. ...
